Specific embodiment
Following steps are only to illustrate the technical solution of the disclosure, rather than its limitations;Although referring to These steps
The disclosure is described in detail, but those skilled in the art should understand that: it still can be to aforementioned each step
Technical solution documented by rapid is modified, or equivalent substitution of some or all of the technical features;And these
It modifies or replaces, the range of each step technique scheme of the disclosure that it does not separate the essence of the corresponding technical solution.
In the detection of index in 1 sperm of embodiment
Then collecting semen first washs sperm using phosphate buffer, then 4 DEG C (low temperature can increase sperm
Survival rate), 850rpm/min is centrifuged 5min, and removal refining (survival rate of sperm can be improved in removal refining) obtains sperm, so
After be diluted, former smart dilution (0.25 hundred million/ml) is shaken up into the rear big EP pipe of each sample 10ml and is kept sample 8ml or so, per big
Pipe sample is managed after shaking up again with the small EP pipe packing 5 of 2ml, and every pipe packing 1.5ml or so places into 17 DEG C of preservations, detects within 1-5 days
When same sample daily only take 1 tubule come out detected.
Dilution is glucose-sodium citrate-yolk liquid (cryo-conservation), concrete component and proportion are as follows:
Basal liquid: sodium citrate 0.5g;Glucose 5g;Distilled water 100mL;
